如何在docker-compose中为我现有的外部网络的容器设置静态IP？

如何解决如何在docker-compose中为我现有的外部网络的容器设置静态IP？

我有以下docker-compose.yml（用于创建VPN客户端可以访问的VPN + docker网络）：

version: "3" 
services:   wireguard:
    image: linuxserver/wireguard
    container_name: wireguard
    cap_add:
      - NET_ADMIN
      - SYS_MODULE
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=America/Santiago
      - SERVERURL=auto #optional
      - SERVERPORT=51820 #optional
      - PEERS=5 #optional
      - PEERDNS=auto #optional
      - INTERNAL_SUBNET=10.13.13.0 #optional
    volumes:
      - ./config:/config
      - ./lib/modules:/lib/modules
    ports:
      - 51820:51820/udp
    sysctls:
      - net.ipv4.conf.all.src_valid_mark=1
    restart: unless-stopped

以上内容构成了一个名为 wireguard_default 的网络：

"Name": "wireguard_default","Id": "ecc19ea95073e2c1ba785fe240c29027f39d1b47977b0f1bdff5c064d6188e81","Created": "2020-08-15T20:59:36.238911179Z","Scope": "local","Driver": "bridge","EnableIPv6": false,"IPAM": {
            "Driver": "default","Options": null,"Config": [
                {
                    "Subnet": "172.23.0.0/16","Gateway": "172.23.0.1"
                }
            ]
        },

因此，我创建了一个网络服务器，其内容如下：

version: '3'

services:
  web:
    container_name: web
    image: nginx
    restart: unless-stopped
    expose:
      - "80"
    volumes:
      - ./:/usr/share/nginx/html:ro
    networks:
      default:

networks:
  default:
    external:
      name: wireguard_default

撰写该邮件会自动设置一个IP，当我连接到VPN时，该IP允许从我的浏览器（http://172.23.0.3）访问网络。

                    "Gateway": "172.23.0.1","IPAddress": "172.23.0.3","IPPrefixLen": 16,"IPv6Gateway": "","GlobalIPv6Address": "","GlobalIPv6PrefixLen": 0,"MacAddress": "02:42:ac:17:00:03","DriverOpts": null

到目前为止，一切正常。但是我需要在Web服务器中为Nginx容器设置一个STATIC IP（例如：172.23.0.25）。

我该如何在组合中设置一个静态IP，使其可以连接到VPN Compose创建的外部网络？

解决方法

是的！

我明白了。

我只是编辑VPN组成，以在“网络”选项中添加子网：

version: "3" 
services:   wireguard:
    image: linuxserver/wireguard
    container_name: wireguard
    cap_add:
      - NET_ADMIN
      - SYS_MODULE
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=America/Santiago
      - SERVERURL=auto #optional
      - SERVERPORT=51820 #optional
      - PEERS=5 #optional
      - PEERDNS=auto #optional
      - INTERNAL_SUBNET=10.13.13.0 #optional
    volumes:
      - ./config:/config
      - ./lib/modules:/lib/modules
    ports:
      - 51820:51820/udp
    sysctls:
      - net.ipv4.conf.all.src_valid_mark=1
    restart: unless-stopped

networks:
  default:
    ipam:
      config:
        - subnet: 172.23.0.0/24

并在要连接的每个docker的compose networks选项中添加静态IP。

version: '3.7'

services:
  web:
    container_name: web
    image: nginx
    restart: unless-stopped
    expose:
      - "80"
    volumes:
      - ./:/usr/share/nginx/html:ro
    networks:
      default:
        ipv4_address: 172.23.0.25


networks:
  default:
    external:
      name: wireguard_default
